[users@httpd] How to retrieve IP address of incoming packets in text file using
httpd source code
Hi,
I am working on Apache httpd web server source code i.e. "httpd-2.2.23" for
my thesis.
I want to retrieve the IP addresses of the Clients from which the requests
are coming to web server and want to save it in a text file. How it can be
done using source code.
Please let me know the file of source code through which i can get it.
Thanks,
Bhavna

I have not used any PHP command up till now. I was trying to make it work
using the apache(httpd) source code itself.
Can it be done without using any script language?? OR by adding some code
lines in the apache source code files itself??

Hi Bhavna,
>> I need the source code file of apache which accepts requests and through which I can get the IP at the initial stage.
i think you looking for that <path-to-http-2.2.23>/server/listen.c line 174
173 #ifdef MPM_ACCEPT_FUNC
174 server->accept_func = MPM_ACCEPT_FUNC;
175 #else
176 server->accept_func = NULL;
177 #endif
for unix environnment MPM_ACCEPT_FUNC is defined on
<path-to-http-2.2.23>/os/unix/unixd.c
AP_DECLARE(apr_status_t) unixd_accept(void **accepted, ap_listen_rec *lr,
514 apr_pool_t *ptrans)
515 {
516 apr_socket_t *csd;
517 apr_status_t status;
518 #ifdef _OSD_POSIX
519 int sockdes;
520 #endif
521
522 *accepted = NULL;
523 status = apr_socket_accept(&csd, lr->sd, ptrans);
524 if (status == APR_SUCCESS) {
525 *accepted = csd;
526 #ifdef _OSD_POSIX
527 apr_os_sock_get(&sockdes, csd);
528 if (sockdes >= FD_SETSIZE) {
529 ap_log_error(APLOG_MARK, APLOG_WARNING, 0, NULL,
530 "new file descriptor %d is too large;
you probably need "
531 "to rebuild Apache with a larger FD_SETSIZE "
532 "(currently %d)",
533 sockdes, FD_SETSIZE);
534 apr_socket_close(csd);
535 return APR_EINTR;
536 }
537 #endif
i am newbie on httpd source code but in C language accept is the main
entry of all client so i think is the entry of all client of httpd
and according to <path-to-apr-1.4.6>/network_io/unix/sockets.c
apr_status_t apr_os_sock_get(apr_os_sock_t *thesock, apr_socket_t *sock)
{
*thesock = sock->socketdes;
return APR_SUCCESS;
}
so after this
527 apr_os_sock_get(&sockdes, csd);
528 if (sockdes >= FD_SETSIZE) {
you could put your code there. Client socket is sockdes and is correctly set
I hope my help could be useful to you

You may want to update that.
Since 2.4, apache makes the distinction between the the two different
REMOTE_ADDR candidates: the peer making the TCP connection,
and the client making the HTTP request. In other words, the nearest
proxy and the end-user. The latter is of course very easy to spoof,
but is nevertheless the one most applications want.
To the OP, if you can't figure it out from what you've already been told,
hire a techie. You probably just want a competent sysop.

Maybe I'm missing something following this discussion, but doesn't the
following PHP command fetch the information you need? If so, I'm sure the
same results can be obtained in other scripting languages.
$_SERVER['REMOTE_ADDR'];

text file using httpd source code
Posted by Bhavna Saini <bh...@gmail.com>.
Thanks for the info.
I have gone through customlog and i understand that it is used to log the
IP and other parameters,
But I want to compare the IP address of incoming requests with IP address
present in a pre-built data structure. After comparing, the request will be
served accordingly.
Therefore, I need the source code file of apache which accepts requests and
through which I can get the IP at the initial stage.
It would be really helpful if you could provide me this info.
Thanks,

Eric is saying that normally only root can write to the root file
system directory '/', and therefore a child process, typically running
as apache or www, would not be able to write to it.

Why would you want to edit source code to do that?
CustomLog logs/ip_request.log "%a %U"
http://httpd.apache.org/docs/2.2/mod/mod_log_config.html#customlog
This would create a file at $SERVER_ROOT/logs/ip_request.log with
contents like so:
192.168.1.1 /index.html
192.168.1.10 /favicon.ico

Hi Eric,
In the previous mail you mentioned that "webserver can't write to /file.txt
from a child process". I couldn't get it properly. Please give some more
details of it.
Actually I want to retrieve the IP addresses of incoming requests as soon
as it reaches the server and want to save it in a file. Please let me know
using which source code file of apache web server I can perform it.
Thanks,

Your webserver can't write to /file.txt from a child process.

Posted by Bhavna Saini <bh...@gmail.com>.
Thanks Eric. I need.one more help.
In mod_log_config file, I found "r->connection->remote_ip" and
"r->connection->local_ip" fields. To retrieve the values of these fields i
wrote a small code in "mod_log_config" file itself under "static const
char*log_remote_address(request_rec *r,
char *a)" which is as follows:
{
File *fp;
fp=fopen("/file.txt","a");
fprintf(fp,"%s",r->connection->remote_ip);
flose(fp);
}
after that I compiled the whole httpd source code using "make" command, it
worked fine without any error. Then i sent request to the server from
different system, even than the file.txt didn't create nor the IP address.
Please let me know if I am doing it right or wrong. How do i perform it, so
that i can get IP addresses of all incoming requests as soon as they arrive
the server.
Thanks

mod_log_config writes out IP addresses to the log. You could read the
same data in any hook.
